Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply voltages.
Applies to VDD_CORE pins.
Applies to pins VDD_RTC, VDD_RTCCORE, and VDD_RTCOSC.
Applies to pins VDD_COREFXD, VDD_OSC, VDD_PLL397, VDD_PLLHCLK, and VDD_PLLUSB.
Applies to VDD_EMC for SDR SDRAM and SRAM controllers
Applies to VDD_EMC, and VDD_IOC domain.
Applies to VDD_IOA, VDD_IOB, VDD_IOD voltage domains. Voltage domains VDD_IOA, VDD_IOB, VDD_IOD must operate at the
same voltage; VDD_IOA = VDD_IOB = VDD_IOD.

voltage for the pin must be present.
The LPC32x0 has no power sequencing requirements, that is, V
and V
takes care that the system correctly powers up in the absence of core power. During IO
power-up this circuit takes care that the system is powered in a defined mode. The same
is valid for core power-down.
